Workers at the Fairmont Miramar Hotel in Santa Monica and four other Los Angeles area hotels have voted to authorize a strike at the hotel properties.

Unite Here Local 11 officials said 81 percent of workers at the Fairmont Miramar, Wilshire Plaza, Sportsmen Lodge, Holiday Inn Downtown Los Angeles and Manhattan Beach Marriott hotels voted to authorize a strike.

Workers at the five hotels have been working under an expired contract since last year, according to the union.

Thousands of workers at more than a dozen other Los Angeles area hotels have ratified new union contracts within the last year.

The new union contracts include wage increases of $2.30 an hour over a three-year period for non-tipped employees, maintenance of free family heath insurance and changes to the housekeeper workload, Unite Here officials said.

“These negotiations are an effort by the workers and the union to take a step toward lifting workers above the poverty line and addressing issues of housekeeper workload,” said Tom Walsh, secretary-treasurer of Unite Here Local 11. “It is a shame that these five hotels have taken such a strong stance against the workers who work hard every day to make their hotels profitable.”

A spokesman for the Hotel Association of Los Angeles, the organization which represents the hotels, was not immediately available for comment on the strike.
